Title: Sludge sucking apparatus
Inventor: TAKEMURA KOJI
IPC: C02F11/00
Filed: 1989-06-01
Abstract: PURPOSE:To permit sludge to be discharged rapidly even from the sewage in a well liquid state by a method wherein a tank is provided with an air release valve fitted with a check mechanism which is brought into communication with an operating chamber and outside air when a piston moves in a position near the end of the tank on the door side and wherein a door is provided with a contacting piece releasably engageable with the air release valve. CONSTITUTION:To discharge sludge from the sewage in a well liquid state, the valve 4c of a sewage run-off pipe 4b provided below a door 1b is opened instead of the door 1b. At the same time, air is supplied from a compressor into an operating chamber 3 to apply pressure to the inside of a sludge chamber 4 by a piston 2. At this time, since an air release valve contacting piece 6 of the door 1b is held against the lid 5a of an air release valve 5, the air release valve 5 will not open even when the pressure of the sludge chamber 4 becomes higher and, by applying pressure to the sewage, it is discharged rapidly from a tank 1. Upon completion of sewage discharge, the compressor is stopped, the excessive high pressure air is forced out from the sewage run-off pipe 4b and the inner pressure of the sludge chamber 4 is reduced to atmospheric pressure, thereby bringing the operation to an end.

Title: Pattern forming method
Inventor: ISHIBASHI AKIRA
IPC: H01J37/30
Filed: 1989-05-31
Abstract: PURPOSE:To form a pattern of extremely thin width without generating failure like disconnection caused by foreign matter, by a method wherein the position of foreign matter is recognized by detecting secondary electron or reflected electon generated from the foreign matter existing on a substrate, and a pattern is formed by projecting a charged particle beam so as to detour around the foreign matter. CONSTITUTION:By projecting a charged particle beam 2 in the form of a line on a substrate 1 in an atmosphere containing gas state material, a pattern 3 constituted of material produced on a substrate 1 from the above material is formed. In such a pattern forming method, the position of foreign matter 4 is recognized by detecting secondary electron or reflected electron generated from the foreign matter 4 when the foreign matter on the substrate 1 is irradiated with the charged particle beam 2. A pattern 3 is formed by projecting the charged particle beam 2 so as to detour around the foreign matter 4. For example, in the vicinity of a position where the secondary electron or the reflected electron sharply increases, the electron beam 2 is a little deflected. In the direction wherein the amount of the detected secondary electron or the reflected electron is decreased, the electron beam 2 is moved, thereby detouring around the foreign matter 4.
